Main Digest

Nearly half the world's adults will experience lower urinary tract symptoms by 2018 - Study provides detailed projections for North and South America, Africa, Asia and Europe.

Nearly half of all adults over 20 will experience at least one lower urinary tract symptom by 2018 - an estimated 2.3 billion people and a worldwide increase of 18% in just one decade - according to research in the October issue of the urology journal BJUI.

Other issues like incontinence will also increase, with South America, Asia and the developing regions of Africa particularly affected by the conditions, which are more common as people get older.

"Our study suggests that urinary and bladder symptoms are already highly prevalent worldwide and that these rates will increase significantly as the population ages" says lead author Dr Debra E Irwin from the Department of Epidemiology at the University of North Carolina, USA.

"These findings raise a number of important worldwide issues that will need to be tackled, as a matter of urgency, by clinicians and public health experts if we are to prevent, and manage, these conditions."

The research team calculated the numbers and prevalence of individuals aged 20 years plus affected by each condition in 2008, using data on gender and age from two key sources:

The data was then extrapolated to provide 2013 and 2018 estimates for lower urinary tract symptoms (LUTS), over-active bladder (OAB), urinary incontinence (UI) and LUTS suggestive of bladder outlet obstruction (LUTS/BOO), using the current symptom definitions from the International Continence Society.

"It is well known that people do not always seek medical attention for urinary problems, so basing our figures on studies using self-reported symptoms is an effective way of measuring worldwide prevalence" explains Dr Irwin.

Key findings of the analysis include:

"We believe that our study underlines the clear and urgent need to improve the awareness, prevention, diagnosis and management of these conditions" says Dr Irwin, who worked with co-authors from the USA, UK and Sweden.

"International and national programs that increase public awareness, educate clinicians and implement public health campaigns that tackle the social stigma of LUTS, will be a significant step towards reaching this objective.

"These public health programs would need to be adapted by region, because countries often differ in their healthcare resources, treatment guidelines and social perceptions."

The full paper on the study, which was funded by Pfizer, provides detailed breakdowns of individuals with LUTS by gender and year. It also provides further statistics on the increases expected by 2013.
